How to correct "ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)" on Mac OS X

I tried to install mysql using home-brew. Everything was successful But could not connect to the server. Obviously server have not started.

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

Sigh..

Following command rescued me..

mysqld stop
mysql.server start

I found it in this stack overflow answer.
